[#18277] Segfault crash by editing mesh with subsurf+ParticleInstance modifiers

particleInstanceModifier_applyModifier uses getVertCo,which is not implemented by ccgDM.

getVertCo was used to simply perform a min/max, so it was fixed to use the apropriate min/max
dm->getMinMax(dm, min_r, max_r);


Maybe the fact ccgDM doesn't implements getVertCo/getVertNo is a bug, since it implements every
other DM function and its strange those are left out.
